Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-7 The present invention provides a technical solution: a detection and early warning device for damage of an anti-corrosion lining of a tank of a transport vehicle, comprising a fixed column 1, a base 2 is installed at the bottom of the fixed column 1, an adjusting groove 10 is provided inside the base 2, a storage groove 8 is provided at the top of the fixed column 1, a top cover 3 is provided at the top of the fixed column 1, a feedback component is provided inside the adjusting groove 10, a cylindrical cavity 17 is provided on the inner top surface of the adjusting groove 10, a drainage component is provided inside the cylindrical cavity 17, a transmission groove 4 is provided on one side of the fixed column 1, and an induction detection device is provided inside the transmission groove 4; The transmission groove 4 passes through the outside of the fixed column 1, and an arc-shaped scale plate 6 is provided on the outer surface of the fixed column 1.

The protective lens 5 is located on the inner side of the arc-shaped scale plate 6, and the outer surface of the protective lens 5 is in contact with the outer surface of the arc-shaped scale plate 6.

[0020] The effect achieved is that, by setting up an induction detection device, it is possible to detect whether there is a small current generated by wear on the tank body, so as to make corresponding operations. When a small current is detected, the current value is reflected by the reflector 31 to the arc scale plate 6, and the value can be read. At the same time, the feedback component will be triggered to turn on the drainage component and contact the safety facilities at the outlet of the drainage component, so that the insulating coolant can flow out smoothly, and the outer surface of the protective lens 5 and the outer surface of the arc scale plate 6 are fitted together, so that the arc scale plate 6 can be installed on the fixed column 1 to prevent gaps from being generated at the installation joint.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the drainage assembly includes a cylindrical rod 19, which is slidably connected between the inner walls of the cylindrical cavity 17, a rubber buffer sheet 21 is provided on the inner top surface of the adjusting groove 10, and an annular groove 22 can be provided on the outer surface of the cylindrical rod 19 near the bottom edge, and the inner side of the rubber buffer sheet 21 is engaged with the inner part of the annular groove 22. A spring 18 is fixed on the top of the cylindrical rod 19, and the top of the spring 18 is fixed to the inner top surface of the cylindrical cavity 17. A through hole 9 is provided on the inner bottom surface of the storage groove 8, which penetrates into the inside of the adjusting groove 10, and the bottom of the through hole 9 is located above the rubber buffer sheet 21. A docking hole 20 is provided on one side of the cylindrical rod 19, which penetrates to the other side. A guide hole 12 is provided inside the fixed column 1, one end of the guide hole 12 penetrates to the outside of the fixed column 1, and the other end of the guide hole 12 penetrates to the inside of the adjusting groove 10, and the guide hole 12 and the cylindrical cavity 17 penetrate each other. A docking pipe 16 is provided on the outer surface of the fixed column 1, and the docking pipe 16 is connected to the guide hole 12.

[0022] The effect achieved is that when the cylindrical rod 19 slides downward, the docking hole 20 on the cylindrical rod 19 is connected with the guide hole 12, and then the insulating coolant in the storage tank 8 is discharged to the outside, and the heat-generating components of the tank truck are cooled. The bottom of the through hole 9 is penetrated into the inside of the adjustment tank 10, and a rubber buffer sheet 21 is arranged at the bottom, so that the insulating coolant can be buffered when it is discharged to the outside. A docking pipe 16 is arranged on the outer surface of the fixed column 1, and the discharged insulating coolant can be transported by connecting the docking pipe 16 to the external pipeline.

[0023] like Figure 2 and Figure 5 As shown, the feedback component includes an arc-shaped metal sheet 23, which is arranged inside the adjustment groove 10, a copper column 7 is fixed on the outer surface of the base 2, one end of the arc-shaped metal sheet 23 is fixed to one end of the copper column 7, and the other end of the arc-shaped metal sheet 23 slides through to the outside of the base 2, a pad 11 is fixed to the inner bottom surface of the adjustment groove 10 near one side edge, the top of the pad 11 and the bottom end of the arc-shaped metal sheet 23 are in contact with each other, a sliding cavity 24 is provided inside the base 2 near one side edge, a wedge block 25 is slidably provided on the inner bottom surface of the sliding cavity 24, the bottom of the wedge block 25 is fixed on the arc-shaped metal sheet 23, a reciprocating groove 13 is provided on the inner top surface of the sliding cavity 24, the reciprocating groove 13 is connected with the guide hole 12, a lead strip 14 is slidably provided inside the reciprocating groove 13, a through-opening 15 is provided on one side of the lead strip 14 near the top edge, and the through-opening 15 is opposite to the guide hole 12.

[0024] The effect achieved is that the arc-shaped metal sheet 23 is a composite material composed of two or more metals or other materials with suitable properties. Since the thermal expansion coefficients of the component layers are different, when the temperature changes, the deformation of the active layer is greater than that of the passive layer, so that the entire arc-shaped metal sheet 23 will bend toward the passive layer, and the curvature of the composite material changes to produce deformation. When an electric current passes through the arc-shaped metal sheet 23 to produce bending, one end of the arc-shaped metal sheet 23 will slide toward the outside of the base 2, thereby driving the wedge block 25 to lift the lead strip 14 upward until the through-hole 15 is opposite to the guide hole 12, and the insulating coolant can be discharged outward.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the induction detection device includes two magnetic poles 26, which are arranged on the inner bottom surface of the transmission slot 4 near the two side edges, and arc-shaped openings 27 are opened on the opposite sides of the two magnetic poles 26. A fixed iron core 28 is installed on the inner bottom surface of the transmission slot 4, and the fixed iron core 28 is located between the two arc-shaped openings 27. A suspension wire 29 is fixed between the top of the fixed iron core 28 and the inner top surface of the transmission slot 4. A moving coil 30 is rotatably arranged on the top of the fixed iron core 28, and the moving coil 30 is located on the outside of the suspension wire 29. A plurality of bridges are arranged inside the moving coil 30. The plurality of bridging sheets 35 are connected to the suspension wire 29, a reflector 31 is arranged on the front side of the moving coil 30, a laser lamp 36 is arranged on the inner top surface of the transmission slot 4 near the outer edge, a copper patch 32 is arranged on the outer surface of the moving coil 30 near the top edge, two first electrodes 33 are fixed on the inner top surface of the transmission slot 4, both ends of the two first electrodes 33 are correspondingly fitted with the outer surface of the copper patch 32, and two second electrodes 34 are fixed on the inner top surface of the transmission slot 4, and the two second electrodes 34 are correspondingly located on the diagonally opposite sides of the first electrode 33.

[0026] The effect achieved is that it can detect whether there is current flowing through the tank body, and the moving coil 30 is rotated through the two magnetic poles 26. When the moving coil 30 rotates, the two second electrodes 34 are turned on, and then the first electrode 33 is cut off. When the moving coil 30 rotates, the light generated by the laser lamp 36 is reflected to the arc scale plate 6 through the reflector 31, and then the current value is obtained. By using an extremely fine metal suspension wire 29, since the suspension wire 29 is thin and long, the resistance torque is very small, so the friction when the moving coil 30 rotates can be reduced. When the suspension wire 29 and the moving coil 30 are connected to each other, the inner side of the moving coil 30 is connected to the suspension wire 29 through the bridge piece 35, so that the suspension wire 29 and the moving coil 30 are connected as a whole, so as to avoid twisting of the connection part between the moving coil 30 and the suspension wire 29 when the moving coil 30 rotates, which interferes with the selection torque of the connection between the two ends of the suspension wire 29 and causes shaking.

[0027] The main problem solved by this embodiment is: first, the two ends of the moving coil 30 are connected to the tank body, the first electrode 33 is connected to the resistance circuit inside the tank car, and the second electrode 34 is connected to the arc-shaped metal sheet 23. After the tank body is worn, a small current will appear. After the small current passes through the moving coil 30, it will rotate under the action of the two magnetic poles 26, thereby cutting off the first electrode 33 and connecting the second electrode 34, thereby driving the drainage component to discharge the insulating coolant to the outside to cool the resistive heating component. When detecting, the suspension wire 29 is connected to the moving coil 30, which can improve the accuracy of detection and capture small currents. For example, in one embodiment, the present invention further provides a method for detecting and warning damage of an anti-corrosion lining of a transport vehicle tank, which is applied to the above-mentioned device for detecting and warning damage of an anti-corrosion lining of a transport vehicle tank, and comprises the following steps: Step S1: First, connect the two ends of the moving coil 30 to the tank body, connect the first electrode 33 to the resistance circuit inside the tank car, and connect the second electrode 34 to the arc-shaped metal sheet 23. When the tank body is worn, a small current will appear. After the small current passes through the moving coil 30, it will rotate under the action of the two magnetic poles 26, thereby cutting off the first electrode 33 and connecting the second electrode 34, thereby driving the drainage component to discharge the insulating coolant to the outside to cool the resistive heating component; Step S2: When the induction detection device is working, the two magnetic poles 26 are used to rotate the moving coil 30. When the moving coil 30 rotates, the two second electrodes 34 are turned on, and the first electrode 33 is cut off. When the moving coil 30 rotates, the light generated by the laser lamp 36 is reflected to the arc scale plate 6 through the reflector 31, and the current value is obtained. Step S3: When the feedback component is working, when the second electrode 34 is turned on, the arc-shaped metal sheet 23 will be deformed downward, so that the cylindrical rod 19 will slide downward. At the same time, when the arc-shaped metal sheet 23 is deformed, one end will slide toward the outside of the base 2, and the sliding will drive the wedge block 25 to slide, so that the lead strip 14 will be lifted upward until the through hole 15 on the lead strip 14 is connected with the guide hole 12, and the outlet of the drainage component can be opened; Step S4: When the drainage assembly is working, when the cylindrical rod 19 slides downward, the docking hole 20 on the cylindrical rod 19 is connected with the guide hole 12, and then the insulating coolant in the storage tank 8 is discharged to the outside to cool the heat-generating components of the tank truck.

At the same time, when the arc-shaped metal sheet (23) is deformed, one end thereof is driven to slide toward the outside of the base (2), and the sliding movement drives the wedge-shaped block (25) to slide, thereby lifting the lead strip (14) upward until the through opening (15) on the lead strip (14) and the guide hole (12) are connected to each other, thereby opening the outlet of the drainage component; Step S4: When the drainage assembly is in operation, the docking hole (20) on the cylindrical rod (19) and the drainage hole (12) are connected to each other when the cylindrical rod (19) slides downward, thereby discharging the insulating coolant in the storage tank (8) to the outside, thereby cooling the heat generating components of the tank truck.
